Show moreObjective Severe secondary tricuspid regurgitation (STR) causes significant right atrial (RA) volume overload, resulting in structural and functional RA-remodelling. This study evaluated whether patients with severe STR and reduced RA function, as assessed by RA-reservoir-strain (RASr), show lower long-term prognosis. Methods Consecutive patients, from a single centre, with first diagnosis of severe STR and RASr measure available, were included. Extensive echocardiographic analysis comprised measures of cardiac chamber size and function, assessed also by two-dimensional speckletracking strain analysis. Primary outcome was all-cause mortality, analysed from inclusion until death or last follow-up. The association of RASr with the outcome was evaluated by Cox regression analysis and Akaike information criterion. Results A total of 586 patients with severe STR (age 68±13 years; 52% male) were included. Patients presented with mild right ventricular (RV) dilatation (enddiastolic area 13.8±6.5 cm2 /m2 ) and dysfunction (freewall strain 16.2±7.2%), and with moderate-to-severe RA dilatation (max area 15.0±5.3 cm2 /m2 ); the median value of RASr was 13%. In the overall population, 10-year overall survival was low (40%, 349 deaths), and was significantly lower in patients with lower RASr (defined by the median value): 36% (195 deaths) for RASr ≤13% compared with 45% (154 deaths) for RASr >13% (log-rank p=0.016). With a median follow-up of 6.6 years, RASr was independently associated with allcause mortality (HR per 5% RASr increase:0.928; 95% CI 0.864 to 0.996; p=0.038), providing additional value over relevant clinical and echocardiographic covariates (including RA size and RV function/size). Conclusions Patients with severe STR presented with significant RA remodelling, and lower RA function, as measured by RASr, was independently associated with all-cause mortality, potentially improving risk stratification in these patients Show less

Show moreAims Atrial functional tricuspid regurgitation (AFTR) has shown distinctive pathophysiological and anatomical differences compared with ventricular functional tricuspid regurgitation (VFTR) with potential implications for interventions. However, little is known about the difference in long-term prognosis between these two FTR-aetiologies, which was investigated in the current study. Methods and results Patients with severe FTR were divided into two aetiologies, based on echocardiography: AFTR and VFTR. VFTR was further subdivided into (i) left-sided cardiac disease; (ii) pulmonary hypertension; and (iii) right ventricular dysfunction. Long-term mortality rates were compared and independent associates of all-cause mortality were investigated. A total of 1037 patients with severe FTR were included, of which 129 patients (23%) were classified as AFTR and compared with 425 patients (78%) classified as VFTR and in sinus rhythm. Of the 425 VFTR patients, 340 patients (61%) had left-sided cardiac disease, 37 patients (7%) had pulmonary hypertension, and 48 patients (9%) had right ventricular dysfunction. Cumulative 10-year survival rates were significantly better for patients with AFTR (78%) compared with VFTR (46%, log-rank P < 0.001). On multivariable Cox regression analysis, VFTR as well as all VFTR subtypes were independently associated with worse overall survival compared with AFTR (HR: 2.292, P < 0.001 for VFTR). Conclusion Patients with AFTR had significantly better survival as compared with patients with VFTR, as well as all VFTR subtypes, independently of other clinical and echocardiographic characteristics.

Show moreBACKGROUND Left ventricular (LV) dilatation may limit LV reverse remodeling after cardiac resynchronization therapy (CRT). OBJECTIVE The purpose of this study was to evaluate the impact of baseline LV volumes on LV reverse remodeling after CRT and whether this is associated with improved survival. METHODS Patients were stratified into quintiles according to baseline LV end-diastolic volume indexed for body surface area (LVEDVi). LV reverse remodeling was defined as >= 15% reduction in LV end-systolic volume at 6-month follow-up after CRT. Independent associates of LV remodeling were assessed and long-term mortality rates were compared between patients with and without LV reverse remodeling (across LVEDVi quintiles). RESULTS A total of 864 patients were included (mean age 66 +/- 10 years; 657 patients (76%) were male), of whom 101 (12%) were in quintile 1 (<65 mL/m(2)), 272 (32%) in quintile 2 (65-95 mL/m(2)), 247 (29%) in quintile 3 (95-125 mL/m(2)), 151 (18%) in quintile 4 (125-155 mL/m(2)), and 93 (11%) in quintile 5 (.155 mL/m(2)). Patients with larger baseline LVEDVi had worse survival after CRT (log-rank, P = .019). The cumulative 10-year survival was significantly better in patients with vs without LV reverse remodeling (48.7% vs 33.9%; P < .001). Significant LV reverse remodeling was observed in all LVEDVi quintiles. In addition, patients with LV reverse remodeling had superior survival than did patients without LV reverse remodeling, regardless of baseline LVEDVi quintile (log-rank, P < .05 for all). CONCLUSION Many patients with larger baseline LV volumes still show significant LV reverse remodeling after CRT and had superior survival (regardless of baseline LV volumes) than did patients without LV reverse remodeling. Therefore, CRT should not be denied on the basis of severe LV dilatation. Show less

Show moreValvular regurgitation represents an important cause of cardiovascular morbidity and mortality. Imaging is pivotal in the evaluation of native valve regurgitation and echocardiography is the primary imaging modality for this purpose. The imaging assessment of valvular regurgitation should integrate quantification of the regurgitation, assessment of the valve anatomy and function, and the consequences of valvular disease on cardiac chambers. In clinical practice, the management of patients with valvular regurgitation largely relies on the results of imaging. It is crucial to provide standards that aim at establishing a baseline list of measurements to be performed when assessing native valve regurgitation. The present document aims to present clinical guidance for the multi-modality imaging assessment of native valvular regurgitation. Show less

Show moreHeart failure (HF) is among the most important and frequent complications of diabetes mellitus (DM). The detection of subclinical dysfunction is a marker of HF risk and presents a potential target for reducing incident HF in DM. Left ventricular (LV) dysfunction secondary to DM is heterogeneous, with phenotypes including predominantly systolic, predominantly diastolic, and mixed dysfunction. Indeed, the pathogenesis of HF in this setting is heterogeneous. Effective management of this problem will require detailed phenotyping of the contributions of fibrosis, microcirculatory disturbance, abnormal metabolism, and sympathetic innervation, among other mechanisms. For this reason, an imaging strategy for the detection of HF risk needs to not only detect subclinical LV dysfunction (LVD) but also characterize its pathogenesis. At present, it is possible to identify individuals with DM at increased risk HF, and there is evidence that cardioprotection may be of benefit. However, there is insufficient justification for HF screening, because we need stronger evidence of the links between the detection of LVD, treatment, and improved outcome. This review discusses the options for screening for LVD, the potential means of identifying the underlying mechanisms, and the pathways to treatment. Show less

Show moreThe primary mission of the European Association of Cardiovascular Imaging (EACVI) is 'to promote excellence in clinical diagnosis, research, technical development, and education in cardiovascular imaging'. Echocardiography is a key component in the evaluation of patients with known or suspected cardiovascular disease and is essential for the high quality and effective practice of clinical cardiology. The EACVI aims to update the previously published recommendations for training, competence, and quality improvement in echocardiography since these activities are increasingly recognized by patients, physicians, and payers. The purpose of this document is to provide the general requirements for training and competence in echocardiography, to outline the principles of quality evaluation, and to recommend a set of measures for improvement, with the ultimate goal of raising the standards of echocardiographic practice. Moreover, the document aims to provide specific guidance for advanced echo techniques, which have dramatically evolved since the previous publication in 2009. Show less

Show moreDilated cardiomyopathy (DCM) is defined by the presence of left ventricular or biventricular dilatation and systolic dysfunction in the absence of abnormal loading conditions or coronary artery disease sufficient to explain these changes. This is a heterogeneous disease frequently having a genetic background. Imaging is important for the diagnosis, the prognostic assessment and for guiding therapy. A multimodality imaging approach provides a comprehensive evaluation of all the issues related to this disease. The present document aims to provide recommendations for the use of multimodality imaging according to the clinical question. Selection of one or another imaging technique should be based on the clinical condition and context. Techniques are presented with the aim to underscore what is 'clinically relevant' and what are the tools that 'can be used'. There remain some gaps in evidence on the impact of multimodality imaging on the management and the treatment of DCM patients where ongoing research is important. Show less

Show moreBackground: Valvular heart disease (VHD) is an important cause of mortality and morbidity and has been subject to important changes in management. The VHD II survey was designed by the EURObservational Research Programme of the European Society of Cardiology to analyze actual management of VHD and to compare practice with guidelines. Methods: Patients with severe native VHD or previous valvular intervention were enrolled prospectively across 28 countries over a 3-month period in 2017. Indications for intervention were considered concordant if the intervention was performed or scheduled in symptomatic patients, corresponding to Class I recommendations specified in the 2012 European Society of Cardiology and in the 2014 American Heart Association/American College of Cardiology VHD guidelines. Results: A total of 7247 patients (4483 hospitalized, 2764 outpatients) were included in 222 centers. Median age was 71 years (interquartile range, 62-80 years); 1917 patients (26.5%) were >= 80 years; and 3416 were female (47.1%). Severe native VHD was present in 5219 patients (72.0%): aortic stenosis in 2152 (41.2% of native VHD), aortic regurgitation in 279 (5.3%), mitral stenosis in 234 (4.5%), mitral regurgitation in 1114 (21.3%; primary in 746 and secondary in 368), multiple left-sided VHD in 1297 (24.9%), and right-sided VHD in 143 (2.7%). Two thousand twenty-eight patients (28.0%) had undergone previous valvular intervention. Intervention was performed in 37.0% and scheduled in 26.8% of patients with native VHD. The decision for intervention was concordant with Class I recommendations in symptomatic patients with severe single left-sided native VHD in 79.4% (95% CI, 77.1-81.6) for aortic stenosis, 77.6% (95% CI, 69.9-84.0) for aortic regurgitation, 68.5% (95% CI, 60.8-75.4) for mitral stenosis, and 71.0% (95% CI, 66.4-75.3) for primary mitral regurgitation. Valvular interventions were performed in 2150 patients during the survey; of them, 47.8% of patients with single left-sided native VHD were in New York Heart Association class III or IV. Transcatheter procedures were performed in 38.7% of patients with aortic stenosis and 16.7% of those with mitral regurgitation. Conclusions: Despite good concordance between Class I recommendations and practice in patients with aortic VHD, the suboptimal number in mitral VHD and late referral for valvular interventions suggest the need to improve further guideline implementation.
